About Yvan

Are you managing your business on Excel, Access, or VBA macros?

I can build a custom internal tool for you.

No more piling up files, data entry errors, or being the only one who knows how everything works. I consolidate your data in one place, in a tool that adapts to your way of working – not a standard software you have to conform to.

I always start with a free mockup: you can see the concrete results without paying or committing.

What this changes:

  • a single reliable and up-to-date source, shared by the entire team
  • everyone sees only what concerns them
  • connected to your current tools (email, payment, calendar…)
  • no need for an IT department

Why me: former developer, graduate of Centrale Paris and ESSEC, 3 years in SMEs.


I have already developed over 10 internal business tools, including for the consulting firm OuiACT, the association L'Œuvre d'Orient, and the training organization La Taloche.


I use open-source languages as much as possible (React, Supabase, etc.).
